Detailed Description

Class to handle concurrent HTTP requests.

HTTP request maps are arrays that use the following format:

  • method : GET/HEAD/PUT/POST/DELETE
  • url : HTTP/HTTPS URL
  • query : <query parameter field/value associative array> (uses RFC 3986)
  • headers : <header name/value associative array>
  • body : source to get the HTTP request body from; this can simply be a string (always), a resource for PUT requests, and a field/value array for POST request; array bodies are encoded as multipart/form-data and strings use application/x-www-form-urlencoded (headers sent automatically)
  • stream : resource to stream the HTTP response body to
  • proxy : HTTP proxy to use
  • flags : map of boolean flags which supports:
    • relayResponseHeaders : write out header via header() Request maps can use integer index 0 instead of 'method' and 1 instead of 'url'.

MultiHttpClient::run ( array  $req,
array  $opts = [] 
)

Execute an HTTP(S) request.

This method returns a response map of:

  • code : HTTP response code or 0 if there was a serious cURL error
  • reason : HTTP response reason (empty if there was a serious cURL error)
  • headers : <header name/value associative array>
  • body : HTTP response body or resource (if "stream" was set)
  • error : Any cURL error string The map also stores integer-indexed copies of these values. This lets callers do:
    list( $rcode, $rdesc, $rhdrs, $rbody, $rerr ) = $http->run( $req );
    Parameters
    array$reqHTTP request array
    array$opts
  • connTimeout : connection timeout per request (seconds)
  • reqTimeout : post-connection timeout per request (seconds)
    Returns
    array Response array for request

MultiHttpClient::runMulti ( array  $reqs,
array  $opts = [] 
)

Execute a set of HTTP(S) requests concurrently.

The maps are returned by this method with the 'response' field set to a map of:

  • code : HTTP response code or 0 if there was a serious cURL error
  • reason : HTTP response reason (empty if there was a serious cURL error)
  • headers : <header name/value associative array>
  • body : HTTP response body or resource (if "stream" was set)
  • error : Any cURL error string The map also stores integer-indexed copies of these values. This lets callers do:
    list( $rcode, $rdesc, $rhdrs, $rbody, $rerr ) = $req['response'];
    All headers in the 'headers' field are normalized to use lower case names. This is true for the request headers and the response headers. Integer-indexed method/URL entries will also be changed to use the corresponding string keys.
Parameters
array$reqsMap of HTTP request arrays
array$opts
  • connTimeout : connection timeout per request (seconds)
  • reqTimeout : post-connection timeout per request (seconds)
  • usePipelining : whether to use HTTP pipelining if possible
  • maxConnsPerHost : maximum number of concurrent connections (per host)
Returns
array $reqs With response array populated for each
Exceptions
Exception
